Application led May 21,

My invention relates to scrapers, and more particularly to a dirt handling scraper adapted for use in picking up and transporting from one place to another the dirt which must be moved in grading for streets, or in excavations of various kinds, or for Vany other I purpose whatsoever. Y

My invention is particularly adapted to wheeled Scrapers and it has among its salient objects to provide in combination with a scraper, at its opposite sides and running in front thereof, ploughing or digging means adapted to cut and level the surface at the opposite sides andA in front of the scraper bowl and to throw the dirt in front of the scraper, at the same time leaving a smooth path at each end of the scraper for the wheels of the scraper, or other carrying means therefor, to move upon, thus providing a more even track or surface for the' supporting elements of a scraper to move upon; to provide in combination with such ploughing or digging means, means for regulating its operation whereby it can be made to dip into the earth at varying depths and to eX- cavate for the wheels or other carrying elements of a scraper and thereby determine the depth to which the scraper proper will dig and pick up the dirt in front of it as it is moved forward; to provide in such a combination, ploughing and digging means which will cut the earth and direct it inwardly from the extreme outer opposite sides, thus making it possible -to square the sides, or to run close toa curb or wall and to dig away the earth and turn it inwardly in front of the scraper, at the same time leaving a smooth and uniform path for the carrying elements of the scraper to move upon; to provide such improved ploughing or digging means in combination with a scraper without in any way interfering with the dumping or tripping of the vscraper in the usual manner for the purposek of leveling or transporting the load after it has been gathered, or for dumping it after it has reached the place of deposit; to provide incombination with a scraper such improved ploughing and digging means as can be readily controlled by the operator in the usual manner, either 192e. serial No. 364,7cs.

or together, thus making iti-possible to zoperate atone 'side ofascraper,or at` fbothsides thereof, as may be desired and as may be made ynecessary by the `conditions ,of the surface being graded or. worked.v f

ln order to fully explain my invention, I have illustratedthe same in combination 'with al wheeled scraper, `which I rwill now describe. Y e

Figure 1 is a plan .view of a wheeled scraper embodying my invention, one side thereof -liefing broken away yto .reduce `the size of the nfigure; 5 a l f Y Figure 2 is a side elevation Yof said scraper, showing certain adjustments in light broken lines; and .lv Figure is'a-front elevationof what is rshownin llig. l, looking into the front of the scraper. l i a v A llieferringnow-more in detail tothe drawings, the scraper body is designated 4, having end walls, as 5, provided with the curved carrier elements o, upwardly in frontv of the' op- -posite ends, only one being shown, for the` purpose of supporting and carrying.k the fscraper when turned into dumping or leveling positions in the usual and well known manner. This invention is not particularly conn cernediwith the turning orrolling, and dumping mechanism of a scraper and no reference 1 will `bei-made thereto.

`Inthefscraper here shownfor descriptive purposes,11 have shown it supported and carried onwheels 7,7,with a draft frame, desig- ,nated as a whole 8, .and which includes a tongueor coupling member 18, for connecting ythescraper tothe lsource of power formoving it,whether truck, tractor, or other motive power. c

i llhe invention'is Aembodiedin the provision Of a `plough 4or digging member, as 9, having the forwarddrafft members, 10, 11, attached f to the front of the draft frame 8, and vertical lifting means l2, adapted to have adjustably connected'therewith the arm 18, or a rocker member 114:, the other end of Which is fupturned into an operating lever 15,'by means 'n of'which said rocker member 14 canbe rocked `forfthe purpose of lowering or-lifting they plough or digging member 9. VAsecond arm 16 is secured to or made a part of the rockerv ward part of said draft frame for pulling it forwardly. e

members`9,can be operated together, or sepa-9 rately, as conditions may require. Operat-Y ing cables, 16, 16, are attached to the upper ends of the lever portions 15, 15, of said rockl i i er member 14.

In dotted or light broken lines in Fig. 2, I have illustrated, the adj ustmentof the plough or digging means 9,V yand' the path. -it cuts Vfor Ythe yWheel 7 thus lowering the wheel and thereby lowering the. scraper bodyand causing it to dig deeper than when runningon the ,.topof the ground before being; cutaway.

Said plough or digging means. 9 being pivotally connected to the'draft frame by means of its draft members 10 and 11, can be readily raised and lowered through the operation of the, rockermember 14.-, and itslever po-r- K. tions, 13 andz15., as beforevreferred to, andwhen released, said plough or digging mem- ,ber9 is raised bymeans of the spring 17, op-

erating onthe. rocker memberl through the arm 16.

Thus I have provideda simple and practicallmeansifor cutting and preparing the sure i facey over which the carrying members 0fa' :the depth'the scraper digs is also determined, `and whileI- have shown onepform or embodiment. of `the. invention, I amaware changessin details thatmany ofV construction Aand -ar rangement can Abe made without. departing f lfrom the spiritofthe invention, and I d ovnot,

therefore limit the invention Vto thefshowing made for vdescriptive purposes,.except as I .carrier wheels and draft frame-for. moving may be limited by the hereto appendedclaims.

. yI claim:

1. In combination with a.` scraperhavng the same, .of separate: gradi-ng means pivotal- -ly connected to said draft framev at the opposite. sidesof.y said scraper and in front of said wheels for grading pathstherefor, said gradj means being independently adjustable. for

scraper are to. movey and 'by means ofwhich determining the level of the paths for said i wheels.

.2'. In a scraper, av draft frame,A carrier means at its opposite. sides tomove upon the surface, a Vscraper supported below said frame. and between said carrier means, a

plough element positioned in front of each of i l" said carriermeans tocut the surface smooth for saldcarrier means and to turn the cutting I inwardly in frontof said scraper, means upon f Lthedraft. frame for independently adjusting ,said-plough elements, and` means4 pivotallyl :g
